Title: Current sensor
Inventor: HOSHINO NARITOSHI
IPC: H01F38/28
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To provide a small-sized and low-price current sensor capable of detecting a direct current and an alternating current. SOLUTION: This current sensor is composed of a current transformer part 12 formed by winding respectively a primary winding 2 and a secondary winding 3 for carrying a current to a magnetic core 1 forming a closed magnetic circuit, and an asymmetric detection circuit 7 for detecting asymmetry of waveforms of an alternating-current power source 4 connected to the secondary winding 3 through a series resistance 9, for applying an alternating voltage Vin, and a secondary current I2. In the state where a detection current I is not carried in the primary winding 2 of the current transformer part 12, the magnetic core 1 is excited symmetrically on both sides by the alternating-current power source 4. In this state, the waveform of the secondary current I2 becomes symmetrical relative to a time base.  When the detection current I is carried in the primary winding 2, the magnetic core 1 is biasly magnetized on one side, and the waveform of the secondary current I2 becomes asymmetrical relative to the time base. A primary current value, namely, the value of the detection current I can be estimated from the degree of asymmetry of the current waveform.

Abstract: PURPOSE: To make the contact with ground plate stable by providing a through- hole part to a folded flat part and drawing excess solder plating into the through-hole with surface tension so as to uniformize the thickness of solder thereby keeping the accuracy of flatness. CONSTITUTION: Since a through-hole 10 is provided to a flat part 8, excess solder plating of the solder plating 9 deposittted on the flat part 8 by solder dip is drawn into the through-hole 10 by its surface tension.

Thus the check and correction of the deposition state of the solder plating 9 is not required, the quality of the product is improved, the manufacture process is simplified, the cost is reduced and the high electromagnetic shield effect is enhanced. Furthermore, a claw 7 of a chassis case 1 is inserted to hole of the ground plate 3 and a shield cover 4 and caulked to make the case 1 in contact with the flat part 1 and the ground plate 3.

Filed: 1988-03-25
Abstract: PURPOSE:To share an analog digital converter(ADC) by controlling so that the writing timing of a one field memory system and a picture-in-picture system does not be mutually overlapped. CONSTITUTION:When a writing signal 22 having one field of a write timing circuit 2 as a unit, goes to be a high level, a switch 7 is connected to an (a) terminal and a (c) terminal. A video signal A24 is A/D converted with using a clock 27 in an ADC8 and written to a field memory circuit 4. When the signal 22 goes to be a low level, the circuit 4 stops writing and since the switch 7 is connected to a (b) terminal and a (d) terminal, a video signal B28 is inputted to the ADC8. When the signal 22 is the low level, a signal 23 goes to be the high level and a PIP circuit 9 goes to a writing condition. Thus, one ADC8 can be shared by the two systems.

Abstract: PURPOSE:To prevent the incorporation of the defects owing to the rubbing and gap agent of a liquid crystal display having picture element electrodes and wirings connecting to said electrodes, by constituting the display in such a way that the average height in the other region is not higher than the average height of the respective picture element electrodes for the purpose of displaying. CONSTITUTION:An aluminum wiring 55 and a gate part 53 which are susceptible to damage owing to rubbing and gap are made lower than a picture element electrode 56. Therefore, the damaging thereof by the rubbing and the breakdown owing to the concentration of pressure by a gap agent are eliminated. A transistor part 66, a gate polysilicon wiring 62 and a source line 3 are all made low, and have the construction strong to the rubbing. A lower glass substrate, for example, quartz glass is used in this case in the stage of producing the above-mentioned construction; therefore, a hollow construction is made by etching the quartz glass and a transistor is formed on the recess. The similar construction is formed as well by laminating a transparent dielectric material such as polyimide on the quartz glass substrate, and patterning and etching the layer.

Abstract: PURPOSE:To nondestructively detect bonding defective part in plaster boards running through a plaster board manufacturing machine by a method wherein temperature distribution on the plaster board surface is measured. CONSTITUTION:The surface temperature of a running plaster board 2 is measured using an infrared radiation thermometer 1 mounted above the shaping line in a manufacturing machine for the plaster board 2.

The board surface has a tendency to exhibit such widthwise temperature profile in the normal state that the temperature is high at the center and gradually lowered toward both side ends. If the central part includes bonding defect, a temperture distribution characteristic that the temperature is the same or relatively low at the center and raised up and then again lowered toward both side ends is obtained.
